Timing issue ?

I opened up my exaust cover and found that my passenger side camshaft sprocket propeller was broken. How screwed am I ?

 

Need some bigger pictures. And, what are you referring to a the "sprocket propeller"?

 

Yes the propeller I also found a loose bolt in one of the valve holes as well as this ring thing.

 

All of your pictures are so tiny, we'd need a magnifying glass to see them. Any way you can post bigger pics as @ATBAV8 requested?

 

Totally screwed...100%

 

what possibly went wrong ? And what would it need to be fixed ? What was damaged most likely other than sprocket.

 

One of your photos appears to be a bolt lying against a valve. This could bend the valve and destroy the piston. Also metal pieces from the cam phaser could be circulating through the engine.

 

Would that be a head bolt ? They all seem to be there doe. Could that possibly be the reason why my engine randomly turned off with the battery light on and doesnt crank only click ? The engine turned thoe when i bypassed the starter relay so kind of lost. Also what is that metal ring it was loose with another bearing type thing i havent gotten it out just yet. Also is it me or is the timing chain marking’s completely off ? Would I need to rebuild the whole engine ? How can i check for damaged pistons/valves ? Or can i possibly replace only the phaser/sprocket?
